/** * glMapBufferRange maps a GL buffer object range to a ByteBuffer. The old_buffer argument can be null, * in which case a new ByteBuffer will be created, pointing to the returned memory. If old_buffer is non-null, * it will be returned if it points to the same mapped memory and has the same capacity as the buffer object, * otherwise a new ByteBuffer is created. That way, an application will normally use glMapBufferRange like this: * <p/> * ByteBuffer mapped_buffer; mapped_buffer = glMapBufferRange(..., ..., ..., ..., null); ... // Another map on the same buffer mapped_buffer = glMapBufferRange(..., ..., ..., ..., mapped_buffer); * <p/> * Only ByteBuffers returned from this method are to be passed as the old_buffer argument. User-created ByteBuffers cannot be reused. * * @param old_buffer A ByteBuffer. If this argument points to the same address and has the same capacity as the new mapping, it will be returned and no new buffer will be created. * * @return A ByteBuffer representing the mapped buffer memory. */ @CachedResult(isRange = true) @GLvoid @AutoSize("length") ByteBuffer glMapBufferRangeEXT(@GLenum int target, @GLintptr long offset, @GLsizeiptr long length, @GLbitfield int access);
